` IMPROVEMENT IN LAMPs'.

Specification forming part of Letters Patent N o. 195,227, datedSeptember 18, 1877; application filed March 29, 1877.

To all whom it may concern Be it known that I STEPHEN S. NEWTON, ofBinghamton, in the county of Broome and State of New York,have inventedcertain new and useful Improvements in Lamps; and I do hereby declarethat the following is a full, clear, and exact description thereof,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

The object of my invention is to construct a lamp in such manner thatthe oil which overflows or drips therefrom may be prevented from runningdown the outside of the lamp, and it is especially intended to embodyseveral improvements upon the construction shown in my Letters PatentNo. 176,983.

I attain the abovecited object by makingv the lamp in two detachableparts, one of which provides a receptacle for the drip-oil.

Figure lis a vertical section of my im proved lamp. Fig. 2 is a planView of same, showing the ports through which the drippings pass to thereceptacle. Figs. 3, 4, and 5 are vertical sections of slightly-modified constructions. Fig. 6 is a horizontal section of anothermodification.

In the drawings, A is the base or standard of the lamp, and may be ofany ordinary form. This base A is attached to the outer shell B eitherby screwthreads or cement; or the standard A and Youter shell B can becon-` structed of one piece of material. The shell B is preferably madeof glass, and is so formed as to have an annular shoulder, b, near thetop, and a rim, b1, extending above said shoulder to catch thedrippings. The upper face of the shoulder or seat b is corrugated, as atb2, to allow free passage downward of the oil.

C is the oilfount or reservoir within the shell B, and may be attachedthereto in various ways, as seen in Figs. l, 3, 5, and 6.

Referring to Fig. 1, this fount O has at its lower end a screw-threadedhub or boss, C', which engages with-a thread in the recess Bl in shellB, corresponding to said boss. The

fount is supported at its upper end by means of an annular ange, c,which rests upon the seat b. o c1 are perforations through this flangeto permit the oil to pass below it.

` Fig. 3 shows an attachment of fount C to shell B by means of a boss,b3, upon the bot- Itom of the shell, which is screw-threaded and engageswith a thread in recess c2 in the fount.

Fig. 4 shows a method of applying my inl vention to Argand burners. Inthis construction the tube D extends from below the fount O upwardthrough the same, y and is screwthreaded at its lower end to fasten thefount to the shell.

In Fig. 5 the upright portion of shell B and the outer surface ot'fountC are provided with corresponding threads for their attachment. Thesethreads can be so made that the parts of the lamp will be held togetherrmly,

and yet allow space for the downward passage of oil.

This construction obviates the necessity of hubs or bosses, andfurnishesa receptacle, E, for the drip-oil.

The oil which has been collected by any of the devices above describedmay be removed by unscrewing the fount C and emptying the shell B.

The object of my invention can also be accomplished by so constructingthe lamp that the fount and shell shall be fast together, as in Fig. 6,in which the inner face of the shell B is ribbed or iuted vertically, asat B2, to form the desired passages. When the shell is hot the fount Ccan be blown or made fast inside.

A tube, F, through the fount permits the air to escape from thedrip-receptacle. This air-tube can be employed, it' desirable, in any ofthe modifications shown.

The operation of my improved lamp will be readily understood from thedrawings and foregoing description.
